1981 Indianapolis 500
Bobby was part of one of the most controversial finishes in Indy 500 history at the 1981 Indianapolis 500. On lap 149, during a caution period, Bobby and Mario Andretti made their pit stop and headed back to the race. Bobby passed eight cars during the caution, while Mario passed two cars. Unser won the race, but was stripped of it the following morning in favor of second place finisher Mario Andretti. Unser was awarded the win in October 1981, but the controversy and financial impact (Unser once estimated that the commercial endorsements he lost because of the delayed result cost him $1 million) caused him to retire from racing at the end of the year.
